AGU Proposes Orbital Shield to Cut Solar Storm Damage by 50%

Summary
A new AGU-backed study outlines an artificial magnetosphere system in which Earth-orbiting spacecraft would release stored material into the dayside magnetosphere during severe solar storms.
That material would rapidly photoionize into plasma, creating a temporary shield that weakens incoming solar-wind structures such as extreme coronal mass ejections and could reduce storm impacts by 50% or more.
The proposal targets disruptions to satellites, spacecraft, radio links, navigation signals and power grids, aiming to provide a real-time response before geomagnetic storms trigger wider outages on Earth.
Unlike one-off emergency launches, the canister-equipped spacecraft could stay in orbit for years until needed, though the concept still requires further testing and simulations before deployment.
